Description: | Crabs are well known crustaceans found in a variety of shallow coastal environments. Their tough exoskeleton (outer shell) is made out of chitin, a material similar to finger nails. They are predators and scavengers that feed on bivalves and gastropods that they break open with their claws. Crabs are fairly common fossils particularly in Tertiary sedimentary rocks. The specimen shows the underside of the crab, including parts of the legs and claws. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | fossils natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
